DTT is the primary teaching method used in Applied Behavior Analysis (ABA) to teach numerous pre-academic and social skills to children with autism. This app can be used to help teach children with autism, attention deficit disorder (ADD), attention deficit hyperactive disorder (ADHD), or any child who has trouble staying on task.

Finding the right therapy for a child on the autism spectrum can be overwhelming. Only Applied Behavior Analysis (ABA) has years of scientific research proving its effectiveness and is recommended by The National Institute of Mental Health and the Surgeon General. But caregivers quickly learn that well-trained therapists in ABA are expensive and hard to find. During Dr. Brown’s forty years of clinical experience as a Licensed Psychologist he has tried to provide low-cost ABA resources for caregivers so they can do their own ABA. ABA and DTT increases your child's likelihood of being mainstreamed, increases happiness, and gives you hope.


The DTT Pro App is fully automated and has been tested with children with autism at The Children's Treatment Center. This app is designed to be very simple with no distracting stimuli because children with autism (and other disorders) are easily distracted. This app is not designed to be a general-purpose game, but rather a clinically tested training approach for children with a specific type of learning disability.
